Scientists Just Unveiled a New Map of Antarctica, and What's Under is Bigger Than Anyone Expected
- A new high-resolution map reveals Antarctica's buried bedrock and subglacial features in unprecedented detail.
- The map merges satellite data with physics-based ice-flow models to fill past radar gaps.
- A vast bedrock channel in the Maud Subglacial Basin spans about 400 kilometers and 6 kilometers wide.
- Experts say the new map improves understanding of how topography influences ice movement.
- The study strengthens the scientific view that Antarctica’s bed reveals a complex ‘underworld’.
- Researchers compare the new map to viewing Mars topography for the first time.
- The map helps reduce uncertainty from gaps between radar flight lines.
- The research team includes scientists from universities and Antarctic programs.
- The map advances glaciology by providing a consistent continental view.
- The study underscores the potential for improved ice sheet behavior predictions.
